DANGER
This part (Choke coil) generates high voltages.
Never touch this part.
SPECIAL INSTALLATION
SETTING
PUMP DOWN (Refrigerant collecting operation)
Perform the following procedures to collect the refrigerant when moving
the indoor unit or the outdoor unit.
(1) Press the push-button switch (SW2) on the circuit board once.
The LED on the circuit board starts flashing (one second ON/one se-
cond OFF). This indicates the start of PUMP DOWN operation.
When the switch is pressed while the compressor is in operation, PUMP
DOWN operation starts automatically.
When the switch is pressed while the compressor is in stop, the com-
pressor starts to operate automatically, and then move on to PUMP
DOWN operation.
(2) PUMP DOWN operation continues for about 1 minute. When PUMP
DOWN operation is completed, the compressor stops automatically.
Then close the 2-way valve and 3-way valve immediately.
(3) Turn the power off.
TEST RUN
CAUTION
Always turn on the power 12 hours prior to the start of the
operation in order to ensure compressor protection

WARNING
1
Before starting work, check that power is not being
supplied to the indoor unit and outdoor unit.
2
Match the terminal board numbers and connection
cord colors with those of the outdoor unit.
Erroneous wiring may cause burning of the electric
parts.
3
Connect the connection cords firmly to the terminal
board. Imperfect installation may cause a fire.
4
Always fasten the outside covering of the connection
cord with the cord clamp. (If the insulator is chafed,
electric leakage may occur.)
5
Always connect the ground wire.
HOW TO CONNECT WIRING TO THE
TERMINALS
A. For solid core wiring (or F-cable)
(1) Cut the wire end with a wire cutter or wire-cutting pliers, then strip
the insulation to about 25 mm to expose the solid wire.
(2) Using a screwdriver, remove the terminal screw(s) on the terminal
board.
(3) Using pliers, bend the solid wire to form a loop suitable for the
terminal screw.
(4) Shape the loop wire properly, place it on the terminal board and
tighten securely with the terminal screw using a screwdriver.
B. For strand wiring
(1) Cut the wire end with a wire cutter or wire-cutting pliers, then strip
the insulation to about 10 mm to expose the strand wiring.
(2) Using a screwdriver, remove the terminal screw(s) on the terminal
board.
(3) Using a round terminal fastener or pliers, securely clamp a round
terminal to each stripped wire end.
(4) Position the round terminal wire, and replace and tighten the
terminal screw using a screwdriver.

CAUTION
When connecting the power supply cord, make sure that
the phase of the power supply matches with the phase of
the terminal board. If the phases do not match, the
compressor will rotate in reverse and will not be able to
compress.
